55 grain Bergers for 20BR

[dawe11]

The 55 grain Bergers have been out. For a year or so.
What is the best powder for this bullet and the 20 BR case?
Also what is the velocity?

If you go over to Saubier.com they have tons of load info for the 20Br. Adam

For me they have been very finicky to find good loads. My Douglas 9 twist on a Savage PTA shoots 30.2 R15 at around 3680fps in the .2s. My Pacnor 8.5 twist on a Cooper 22 Seems to like 31.7 r17 in the lower 3600s in the .3s. I'm not sure I have found the accuracy node for the Cooper. The Savage I seat at the lands. The Cooper .015 into the lands. These loads are on the warm side so work up. I could not find any consistent accuracy with 8208, H4350, Varget, or Big Game. Hope this helps. I am looking forward to others' posts.

Have been using N540 and R15 and have some success but the case is not filled up to the shoulder. Would like to find a powder that fills the case more, and still get some good velocities.
